Application filed April 28, 1915.

To all whom t may concern.'

Be it known that l, EMRY J. DUNKLEE, a citizen of the United States, and a resident ofI Hackensack, in the county of Bergen and State of New Jersey, have invented a new and Improved Machine for ltenapping` `referred to which is adapted. to be rolled over the Worn portion of a fabric garment so as to providea nap and thereafter trim the same to he uniform with vthe nap of the unworn portions, there being an electrically heated ironing roller associated` with the cutter so that the fabric can be pressed where it is renapped and reinished.

A further object of the invention is the provision of a device which is adapted to be operated by hand by being rolled over the parts to be renapped and rciinished, the device embodying means for adjusting the napping brush andthecutter, whereby the machine can produce nap of any length so l as to match thek unworn parts of the garment, and furthermore, the machine embodies an electric motor which, by means `of clutch devices, can be operatively connected with either the napping brush or the cutter for rotating the same.

With such objects in view, and others which will. appear as the description pro ceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particu` larity in the following description and claims appended hereto.

ln the accompanying drawings, which illustrate one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the Specification of Letters Patent.

views, Figure 1 is a vertical longitudinal section of the machinegliig. 2 is a side view thereof; Fig. 3 is a transverse section on the line Sv, Fig. l; Figs. 4,5 and 6 are detail sectional views respectively on the lines i4-fl, 5 5, 6-6, lig. l; 7 is a detail sectional view of the adjustable lined cutter bar associated with the rotary cutter; and F ig. 8 is a diagrammatic view of the circuity connections. v

Referring to the drawing, A designates the casing or housing of themachine, which housing is preferably, although not necessarily, a metal structure closed at all points except the bottom from which partially protrude the electrically heated ironing roller B, the renapping brush C and the yrotary cutter `D,'which is located at the side of the ironing roller B opposite from the renapping brush C. ln the casing is a box E of inverted |Ushape cross-section, as shown in Fig. 4:, the ends of the box being fastened to the end walls l of the casing A.. Supported on the top .of .this lloox is an electric motor F which supplies the power for rotating the brush and cutter. In use the machine is moved .hack and forth over the goods to be renapped and relinished, the weight of the machine being sustained by the roller B,-and to facilitate the movement larger in diameter than the diameter of the wire winding 3, so that vthe wire will not be in electrical contact with the shell of the ironing roller but the heat from, the current passing through the winding 3 will be i transmitted to ythe cylinder i through the slight interveningv air gap 6. The ironing roller B is set into the box E and the opposite Walls of the latter have supports in the form of screws 7 which screw into the hub bosses 8 of the inner drum. Theheads 5 of the outer drum or shell have bearing openings 9 which fit around the hub extensions 8, so that the outer drum or shell-will be free to rotate while the inner drum is stationary. `Current is supplied to the winding 3 b y leading-in wires 10 which pass into the inner drum through one of the bearing screws 7. The electrically heated'roller B is disposed in a chamber by itself so as to conservethe heat, the walls and top of the chamber being,fas shown in Fig. 1, lined of pieces of asbestos 11 or equivalent material.

. The napping brush C is arranged with its axis horizontal or parallel with the axis of the roller B; and consists of a cylindrical body 12having steelwire bristles 13 of any desired shape or stiffness. The cylinder has a shaft 14, the ends of which are journaled in bearing blocks l5 fastened to the side walls ofthe box E. One endof the shaft protrudes out of the box and has a pulley 16 around which a belt 17 passes. .This belt also passes around a pulley 18 on the shaft 19 of the motor F. `Adjacent the brush C is a parallel gage roller 2O which can be set for governing the depth of penetration of the brushing needles into the cloth to be renapped. The lgage roller 20 has its ends supported in adjustable bearings 21, Fig. 4, which are slidable in guide frames 22 and are adjustable by screws 23 journaled in the frames and have a threaded connection with the bearings 21. These screws are simultaneously rotated so that both ends of the gage roller will be moved to the same extent. The turning of the screws is accomplished by a horizontal shaft 24 provided on its outer end with a handle 25, and on this shaft are worms 26 which mesh with worm gears 27 on the screws 23. When the brush is in use,

as shown in Fig. 1., the rollers B and 20 will rest on the fabric, and as the machine is moved overthe worn part of the fabric the brush,'which rotates at a suitable speed, will tear out or loosen the fibers to form a new nap. f

The rotary cutter D comprises spiral knives 28 fastened to the heads 29 of a spool 30, which spool is fastened to a shaft 31 that carries a pulley 32. Passing around this pulley is a belt 33 which also passes around a pulley 34 on the motor shaft. The `cutter is secured by said screws 35 to the shaft, which latter is journaled in bearing blocks 36 fastened to the side walls of the box E. By taking out the screws the shaft can be removed and the rotary cutter taken out of the machine. The brush C is also remov able from its shaft in the same manner, whereby brushes of different types may be interchanged. The knives 28 of the cutter coperate with a cutting bar 37 which is fastened to bearing blocks 36 and extends horizontally of and under the rotary cutter D, the relation of the cutting bar and knives being similar to a. lawn mower construction. This cutter bar 37 has its edge 37, Fig. 7, adjustable toward and from the knives, the

adjustment being effected by means of screws 38 and 39, whereby horizontal and vertical adjustments are provided. In making these adjustments the securing bolts 40 are loosened, and after the proper adjustments are obtained these bolts are tightened. Cooperating with the rotary cutter D is a gage roller 41 which is adjustably mounted. like the roller 20, whereby the relation of the cuter to the fabric to be refinished can be reguated.

In use the'brush C and cutter D are used independently, and therefore a clutch device is employed to connect either one of these elements with the motor. This clutch device comprises teeth 42 on the motor shaft 19 and teeth 43 and 44 on the pulleys 18 and 34 which are spaced apart on the motor shaft. The pulleys have grooves 45 into which engages a forked shifting member 46 fastened to a horizontally movable bar 47 which is slidable on and transversely of the top of the box E. When the parts are in the position shown in Fig. 3 the pulley 18 is clutched to the motor shaft so that the brush C will be operated, and by moving the controlling rod 47 to the right, Fig. 3, the pulley 34 will be clutched to the motor shaft so that the cutter will be operated. This controller rod 47 has a handle 48 which extends out of the casing A so as to be operable. The controlling rod is held in either of its positions bv a spring clutch 47 engageable in openings 4Fa in the rod 47. This spring catch automatically engages and disengages as the rod 47 is pushed in or pulled out. On the casing are electrical switches 49 and 50 which connect the motor F and heating element or winding 3 independently to a source r,of current supply, as shown in Fig. 8. It

will be understood that the switch .50 is closed only when the ironing roller B is to be used for pressing the fabric after it has been renapped and refinished, and during the use of the napping brush and the rotary cutter `the roller B simply acts as a support for the machine, the heating current being cut off.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes rimase may be made when desired as fall within the scope of the appended claims.
